BRP-PACU Version 2.0.0 Released Today

December 31, 2008

Its been a while since I posted anything about BRP-PACU, a dual channel FFT based Acoustic Analysis Tool to help engineers configure professional sound systems.  I have been using it regularly, but I recently became motivated to improve it.  Here is a list of improvements obtained from the Changelog.

Basically now you don’t need an external pink noise generator or a dual channel capture card.  Just one input should work fine.

Version 2.0.0 Pink Noise and Jack Support (allowing possible Mac OS-X support?)

  • Update on Mac OS-X, my wife’s laptop hasn’t got enough disk space to install macports, xcode, etc, anyone out there who would like to check it out though let me know.
  • Also I need help packaging this for the OS-X and for Linux (deb).

I have a minimal Debian & Xfce based vmware image, which will run on any x86 Mac/Linux/Windows, though.  Not sure how to distribute +850MB of data yet, as ISP’s tend to limit upload bandwidth to a trickle.

Added Pink Noise Output and  the ability to Un/Mute and adjust levels

Added Jack Audio Connection Kit support and removed Alsa (removing need for linux)

  • Automatically connects Reference and Measured inputs to Channel 2 and Channel 1
  • Automatically connects Pink Noise Output to Reference Input and sondcard output
  • This app may now run on a Mac since alsa has been abandoned.  This may require some tweaking.

Major GUI and UI update!

*Delay function now resets delay before each capture, resulting in a much
more intuitive delay finding procedure.

*Rewrote buffer capture interface so that it makes more sense and works
consistently.

*Rewrote keyboard shortcuts so they don’t interfere with the Avg gain.

*Added default zoom button to return to original zoom settings.

*Added inserted delay size status on the status bar.

*Added “about” and “general help” windows

*TODO: ability to save buffers to a file.  Also a VM for windows and Ubuntu packages.
Miscellaneous Bug Fixes and updates.
